I'm not too familiar with the nuts and bolts, but it seems like it would be at least technically possible. After all, hibernation works by dumping RAM and resuming. You would obviously need to set aside one partition for each OS, an area for RAM, and implement a hardware "switcher" process.
In the end though, I think this would still count as virtualization. That third "switcher" process would be like the host OS, and the others would be like the "guests"
